import io
import os

search_for_this_line = 'CCC'

inf_file = io.open("C://file.txt", mode = 'r+')
lines = inf_file.readlines()
index_temp = 0

for line in lines:
    index_temp = index_temp + 1
    print line
    if search_for_this_line in line:
        print "FOUND IT !!!"
        break

inf_file.close()

Later found, file.txt fact is unicode utf-16 (16bit for one character) format, and the python default format open to ANSI (single byte for one character), so there will be a question above, we will begin to open line slightly modified, will pass in a manner encoding

inf_file = io.open("C://file.txt", mode = 'r+',encoding = 'utf-16')

You can find it in this line CCC

Also print out

AAAAAA

BBBBBB

CCCCCC

Absolutely correct.
